GMC makes some of America’s favorite cars, but GMC isn’t perfect, and many of GMC’s cars have issues. Just like other automakers, GMC’s cars can suffer some serious issues that’ll need to be repaired at a hefty cost. Here’s a look at some of the most common problems that the GMC Acadia has.
Gas cap related check engine light issue
According to RepairPal, one of the most common problems that the GMC Acadia can experience is the fact that the check engine light may turn on for a somewhat trivial reason. Rather than a serious issue, what’s actually happening is that the gas cap is loose or worn and it is, for some reason, causing the check engine light to turn on.
This is a very easy fix, as for many owners, it can be fixed by simply tightening the cap. Other owners may have to replace their cap, but that’s not an expensive fix.
What is expensive, however, is the fact that, as owners on RepairPal wrote, GMC service centers are charging people almost $100 just to diagnose the issue. This basically means that diagnosing this issue may be more expensive than actually fixing it.
This problem generally happens when the car has about 66,000 miles on the odometer. It also generally happens to seven model years of the Acadia, which are the 2007 to 2012 model years, and the 2014 model year.
More check engine light issues on the GMC Acadia
RepairPal said that the second most common issue with the Acadia once again has to do with the check engine light. However, unlike the gas cap problem, this issue is more serious and it will probably cost more money to fix, too. Just like the other check engine light problem, this problem mainly affected a handful of model years, namely the 2007 to 2012 model years.
This issue usually happens when the Acadia has about 110,000 miles on the odometer. What happens is the check engine light will turn on, and then it’ll display one of these eight codes: P0011, P0014, P0021, P0024, P0341, P0346, P0336, or P0391.
Unfortunately, rather than just buying a new gas cap, this problem can be one of two things, according to RepairPal. It may mean that the Acadia’s power control module needs an update, or it may mean that its camshaft needs to be corrected.
Regardless of which one of these issues is the culprit, the Acadia will need to get serviced, and it’ll cost a lot. RepairPal wrote that it’ll cost, on average, about $1,700 to fix this issue.
Transmission related check engine light issues
Unsurprisingly, the most common issue with the GMC Acadia happens to do with its check engine light once again. Similar to the other two check engine light issues, this problem affects a handful of model years ranging from the 2007 to 2013 model years and the 2015 model year. This issue also happens on average after the Acadia’s logged about 92,000 miles on the odometer.
However, this was by far the most serious and costly issue with the Acadia. What happens is that the check engine light will turn on and display one of these seven codes: P0716, P0776, P0717, P0777, P2714, P2715, and/or P02723, according to RepairPal. This issue usually involves the clutch wave plate in the Acadia’s transmission breaking down.
As a result, many owners reported their Acadias simply coming to a stop while in the middle of the road. Since this is a transmission issue, it also means that it’s expensive to fix as RepairPal said that a complete transmission rebuild may be necessary. The average cost of this will vary, but most owners reported a price tag that was well in the $2,000 to $4,000 range.
